Kyle Williams, Nigel Bradham remain out for Bills

ORCHARD PARK, N.Y. -- The Buffalo Bills were again without two defensive starters in Thursday's practice.

Defensive tackle Kyle Williams and linebacker Nigel Bradham both were sidelined with knee injuries.

If Williams can't play Sunday, the Bills will use a combination of Corbin Bryant and Stefan Charles at defensive tackle. If Bradham can't play, rookie Preston Brown should start in his place.

The Bills will practice once more Friday before traveling to Detroit on Saturday.
